Communication signal processors and methods compatible with a variety of modulation types

A digital signal processor (20) is provided which is compatible with a large variety of modulation processes (e.g., BPSK, QPSK, pi /4 PSK, M-ary FSK and M-ary PSK). The processor has a transmit section (40) which can convert input data streams into baseband I and Q signals and a receive section (60)...

Beschreibung
Zusammenfassung:	A digital signal processor (20) is provided which is compatible with a large variety of modulation processes (e.g., BPSK, QPSK, pi /4 PSK, M-ary FSK and M-ary PSK). The processor has a transmit section (40) which can convert input data streams into baseband I and Q signals and a receive section (60) which can recover data streams from input baseband I and Q signals. The transmit section includes a direct I/Q modulator (46) and a common phase modulator (44) and the receive section includes an M-FSK to M-PSK converter (350) and a common phase demodulator (72). The processor is particularly suited for realization as an application-specific integrated circuit (ASIC) which can be integrated in multiband, multimode transceivers.
